From: Salvianolic acid B reduced the formation of epidural fibrosis in an experimental rat model
Effect of Sal B on VEGF expression in the epidural scar tissue. The expression levels of VEGF and β-actin in the epidural scar tissue from the four groups (a). The quantitative analysis was performed based on the greyscale value of straps. Compared with the control group, Sal B treating groups showed the significant decrease (*p < 0.05 compared to the control group, **p < 0.05 compared to the control group, ***p < 0.05 compared to the control group) on VEGF expression (b). Values are presented as mean ± standard error of the mean
